1. Yes
2. Being a pedophile in itself is not a crime as far as I know, you have to actually victimize someone, either through sexual contact or perpetuating the spread of child pornography. I don't think """art""" like cartoon porn or smut writing qualifies, though I've never looked into it. You can scream from the rooftops that you want to fuck kids and LEAs can't really do anything about it because it's not a crime to want to fuck kids, just like it's not a crime to want to murder somebody. This is a good thing, because the ability to punish thoughts is not a power a government should have; but it necessarily demands that the society retain some informal means of enforcing morality and correcting deviations from it, such as beating the shit out of pedophiles, which tragically has become frowned upon in clown world.
3. Even if it was a crime, LEAs have bigger fish to fry, like tracking down the people who actually produce actual child porn -- at least on paper.
